SDLC

The Software Development Life Cycle — the sequence of phases through which software is defined, built, verified, deployed, and maintained. Traditionally designed around human teams and largely invariant, it is the reference frame against which AI-era changes are measured as agents compress, reorder, or automate individual phases.

Origin

A foundational software-engineering concept since the 1960s-70s, when development was first formalized into ordered, repeatable phases.
